ROLLS.

SPECIFICATION forming part of Letters Patent No. 583,*738, dated June l,1897.

Application filed August 1,1896.

Serial No. 60l,296. (No model.)

To all whom 't may concern:

Be it known that I, J OSEPH FAwELL, a

citizen of the United States, residing at Pittsburg, in the county ofAllegheny and State of Pennsylvania, have inven ted or discoveredcertain new and useful Improvements in' Rolls, of which improvements thefollowing is a specification.

The invention herein described relates to certain improvements in rolls,more especially such as are employed in the manufacture of tin-plate.

The invention has for its object the protection of the surface of therolls from injury by grease or other lubricant applied to the journalsthereof, and also the protection of the journals from scale, &0. As iswell known in the art, if the rolls become greasy the sheets are spottedin the same manner and will not thereafter take a bright, smoothpolished appearance and, further, it has been found that when pieces ofgrease or other lubricant drop onto the rolls and are carried With thesheet between the rolls the sheet becomes crinkled up and the rolls arethereby scratched or grooved to such an extent as to require theirre-turning. i

The object of the present invention is to interpose a shield between thejournals of the rolls and their reducing-surfaces which will prevent thegrease from coming in contact with the latter; and in general terms theinvention consists in the Construction and combination substantially ashereinafter described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation of a pair of sheet rolls having myimprovement applied thereto. Fig. 2 is an end elevation of the same.Fig. 3 is an elevation of one end of a pair of rolls, showing a certainmodification in my improvement; and Fig. 4 is an elevation of one end ofa pair of blooming-rolls having my improvement applied thereto.

In the practice of my invention the rolls l are constructed in the usualor any suitable manner, having the journals 2 with necks 3.

In the body of the rolls, near the ends of the reducing or operativeportions thereof, are cut grooves 4 at right angles to the aXis of therolls for the reception of the edges of the shield. This shield 5 ismade in two parts or sections vertically and provided with openings, soas to fit around the rolls, the edges of the openings in the shieldprojecting into the grooves 4. The two parts or sections of the shieldare held together by clips 6, bolted to shield, as shown in Figs. 1 and2.

When the grease is applied to the journals 2 of the rolls, thecentrifugal action will cause it to move out toward the periphery of therolls and gradually to work in between the meeting faces thereof. As itencounters the shield it will be prevented by the part of the shieldprojecting in between, and there will be no tendency whatsoever for thegrease to creep down into the groove, as such tendency will be entirelyprevented by centrifugal action.

In lieu of forming the grooves in the body of the rolls, a shoulder 7may be turned at the ends of the bodies and the grooves cut therein, asshown in Fig. 3.

My improvement is also applicable to blooming-rolls to prevent scale andportions of the metal from being thrown as the billet or bloom is beingreduced onto the necks of the rolls. In applying the shield toblooming-ro1ls the groove 4 for the reception of the shield is formed inthe shoulder or collar adjacent to the journals of the rolls, as shownin Fig. 4.

It is characteristic of my improvement that the groove andshield are soarranged that the centrifugal action of the rolls will prevent anytendency of the grease to creep down into the grooves and under theedges of the shield.

I am aware that it is old to close the inner ends of car-axle boxes byplates adapted to surround the axle inside the journals, so as toprevent the entrance of dust, &c., into the box. It is also old to placean annular gutter around the inner ends of journals of an ironing-rollerfor the purpose of preventing clothes from coming into contact With thegreasy journals, said gutter being provided with a drainagetube forconducting away ,any oil that may collect in the gutter; but so far as Iam aware it is not old to form grooves in metal-reducing rolls inside ofthe IOO journals for the recepton of the nner edges of a shield entirelysurrounding each roll and projeetng beyond their periphe'ies.

I claim herein as my nvention- The combination of e pair ofmetal-teamoing rolls having grooves in their body portions adjacent totheir journals, a sheld at each end of the rolis entirely surroundingthe same and projecting beyond their eripheries,the nne* edges of theshields fittng into IO the grooves in the 1'o11s, substantially as setfo'th.

In testmony my hand.

whereof I have hereunto set J OSEPII FAWELL. VVitnesses:
